Editorial summary
Cornerstone Foundation System LLC. is listed at 140 Art Mill Ln in Roseburg as a foundation repair contractor. The profile shows a 4.9 Google rating from 8 reviews and a phone number, but no website, years in business, or service-area text was supplied. With only foundation repair listed, the record does not support broader crawl-space or waterproofing claims. It is still a usable local entry for homeowners comparing structural repair options, especially when they want a company focused on foundation work rather than a larger moisture-control menu. The limited review count means the trust signal is positive but still relatively narrow compared with larger profiles.
